Tarnish...yeah, that's tough. You can't get rid of tarnish completely without grinding it off, and that can be worse for the blade than the tarnish itself. Best thing I've found for blade tarnish is this stuff called Metal Glo. It won't get the spots off completely, but it will reduce them significantly. I've never found Metal Glo in a hardware store, but it's easy to get online.
Atlanta Cutlery sells it for a good price. In any event, the earlier you tackle tarnish the better.
Another thing that helps with tarnish is leaving the blade unsheathed. Moisture can get trapped inside the scabbard where it increases the rate of oxidation, and thus, you get more tarnish and you get it faster. Just make sure you keep the unsheathed blade in a safe place where you won't trip over it! I bet that old shin gunto still has a mean edge on it.
As for gunblades, there was the LaFaucheux Knife Revolver, a pin-fire weapon from 1865 with a long knife built directly into the barrel. I wish I had a good picture to link to, but the thing does look more than a little like a Final Fantasy gunblade.
